The room itself looks more like a prison cell than an apartment. The WiFi works only in theory, I guess the host has only one WiFi router for all the rooms they have so the Internet signal is so weak one can't use it at all.
The building is starting to fall down and our Thai friend said it's in very bad shape "even as for Thai conditions". On the other hand it is very cheap so one shouldn't expect too much (even though the room and building condition was a bad surprise for us when we came).
When it comes to the vicinity - it's great if one wants to live like a local and amongst the locals. A lot of delicious street food, but be aware of the dogs. They sometimes are so absorbed by fighting they don't pay attention to people.
The host tries to be helpful, but doesn't give the impression of true hospitality. For an earlier check - in we had to pay some additional fee and immediately after entering the room we were warned that breaking a glass "will cost you 100 bahts". I know it's business, but some businesses requires being more friendly and open towards the guests.
